| morphological characterization of eustrongylides sp. larvae (nematoda, dioctophymatoidea) parasite of rhinella marina (amphibia: bufonidae) from eastern amazonia. | absctract eustrongylides spp. nematodes have birds as final hosts and uses other vertebrates as intermediate/paratenic host (fish, amphibians and reptiles) and have zoonotic potential. in amphibians, the larvae may be located in the subcutaneous tissues, liver and mesentery, between the muscle fibres, especially in the lower limbs. rhinella marina, which is widely observed in brazil, has exhibited complex diversity in its helminth fauna, reflecting the unique habitat of the amazon biome. for the ... | 2016 | 27334826 |
| patterns of genetic variability in island populations of the cane toad (rhinella marina) from the mouth of the amazon. | the amazonian coast has several unique geological characteristics resulting from the interaction between drainage pattern of the amazon river and the atlantic ocean. it is one of the most extensive and sedimentologically dynamic regions of the world, with a large number of continental islands mostly formed less than 10,000 years ago. the natural distribution of the cane toad (rhinella marina), one of the world's most successful invasive species, in this complex amazonian system provides an intri ... | 2016 | 27073849 |
| rhinella marina (amphibia: bufonidae) versus rhabdias paraensis (nematoda: rhabdiasidae): expanding the view on a natural infection. | amphibian and reptile lungs are frequently infected with rhabdias parasites, and this condition ultimately leads to reduced survival, performance, and growth because of granulomatous inflammation, nodule formation, and nematodal pneumonia onset. here we investigate the histopathological features of naturally infected rhinella marina by the lung nematode rhabdias paraensis. a total of 10 host animals were captured in peridomiciliar areas in the eastern brazilian amazon, and anatomic-histological ... | 2016 | 26959813 |
